It is usually treated with a harness that holds the hips in a safe position so they can develop normally. After the hip is confirmed to be in the correct position, babies are commonly kept in the harness for up to 12 weeks or more. While effective, wearing a harness for this length of time can be challenging for families. It can make everyday care such as feeding, bathing and dressing more difficult, and add stress during an important time for bonding.\n\nThis trial compares two treatment options: 8 versus 12 weeks of harness wear. The 8-week option is being tested because research has shown that most hips appear normal on ultrasound by this point. The main measure of success is whether the hip looks normal on x-ray two years after treatment. Families will also be asked about their experience and treatment-related problems.\n\nIf the shorter option is as effective as the longer option, many babies could spend less time in brace, reducing burden without compromising outcomes. Because this trial is embedded in routine care, results can be put into practice quickly and guide care for babies across Ontario and beyond.",[27,28,29,30,31,32],"Developmental Dysplasia of Hip","DDH","Developmental Dysplasia of the Hip","Developmental Dysplasia of the Hip (DDH)","Hip Dysplasia, Developmental","Hip Dysplasia, Congenital, Nonsyndromic",[34,35,36,37,38,39,40,41,42,43,44],"Pavlik Harness","Pavlik","Brace Treatment","Hip dysplasia","Infant","Paediatric Orthopaedics","Harness treatment","treatment duration","8 weeks","12 weeks","developmental dysplasia of the hip","NOT_YET_RECRUITING","2026-09-23",{"date":48,"type":49},"2026-09-29","ACTUAL",{"date":51,"type":21},"2027-01",{"date":53,"type":21},"2030-03",{"name":55,"class":56},"The Hospital for Sick Children","OTHER",1,{"id":59,"slug":60,"hasResults":11,"nctId":61,"briefTitle":62,"officialTitle":63,"acronym":4,"eligibilityCriteria":64,"healthyVolunteers":11,"sex":16,"minAge":65,"maxAge":66,"enrollmentInfo":67,"targetDuration":4,"studyType":22,"phases":69,"briefSummary":70,"conditions":71,"keywords":4,"overallStatus":45,"whyStopped":4,"lastUpdateSubmitDate":72,"lastUpdatePostDateStruct":73,"startDateStruct":75,"completionDateStruct":77,"leadSponsor":79,"locationsCount":4},"100615180","does-a-6-week-duration-of-hip-spica-immobilization-provide-comparable-clinical-and-radiological-outcomes-to-12-weeks-in-children-undergoing-open-reduction-and-pelvic-osteotomy-for-developmental-dysplasia-of-the-hip-ddh-100615180","NCT07289256","Does a 6-week Duration of Hip Spica Immobilization Provide Comparable Clinical and Radiological Outcomes to 12 Weeks in Children Undergoing Open Reduction and Pelvic Osteotomy for Developmental Dysplasia of the Hip (DDH)?","Comparison of Hip Spica Duration (6 Weeks vs 12 Weeks) Following Open Reduction and Pelvic Osteotomy in Developmental Dysplasia of the Hip","Inclusion Criteria:\n\n* Children 18 months-6 years undergoing open reduction with pelvic osteotomy for DDH.\n\nExclusion Criteria:\n\n* • Infection\n\n  * Paralytic hip dislocation","18 Months","6 Years",{"count":68,"type":21},40,[24],"The study aim is to compare clinical and radiological outcomes of 6-week versus 12-week hip spica immobilization following open reduction and pelvic osteotomy for DDH.",[28],"2025-12-04",{"date":74,"type":49},"2025-12-17",{"date":76,"type":21},"2026-01-01",{"date":78,"type":21},"2027-03-01",{"name":80,"class":56},"Assiut University"]
